Abstract
A noise reduction and exhausting device with the undercut embossment is composed of an air inlet pipe (1), an air inlet end cover (2), a silencer body (3), an air outlet end cover (4) and an air outlet pipe (5), wherein the two ends of the silencer body (3) are provided with the air inlet end cover (2) and the air outlet end cover (4); the air inlet pipe (1) is welded to the air inlet end cover (2); the air outlet pipe (5) is welded to the air outlet end cover (4). The noise reduction and exhausting device with the undercut embossment is characterized in that the position where the air inlet end cover (2) and the silencer body (3) are combined and the position where the air outlet end cover (4) and the silencer body (3) are combined are of an undercut turnup structure. According to the noise reduction and exhausting device with the undercut embossment, waste of raw materials of a silencer is reduced as much as possible, optical radiation and air pollution in the welding process are eliminated, and meanwhile the noise reduction and exhausting effects of the silencer are not weakened. The noise reduction and exhausting device has the advantages of being attractive in appearance and long in service life.
Description
Technical field
The utility model is for the exhaust muffling device of the heavy mechanical equipments such as heavy duty equipment.
Background technique
Silencing apparatus is one of crucial accessory of internal-combustion engine interwoveness, mainly contains the function that reduces exhaust sound and engine exhaust gas is got rid of.When seal failure, the cylindrical shell of silencing apparatus has the situations such as damaged, will cause the noise of internal-combustion engine to surpass the scope that country limits, affect the performance of whole internal-combustion engine, so the integral body manufacture quality of silencing apparatus directly has influence on the performance of internal-combustion engine.In order to adapt to the requirement of heavy machinery outward appearance U.S., the normal welding mode of baffler is improved to the mode of undercut embossing.This makes raw-material saving, eliminate optical radiation and atmospheric pollution in welding, but the exhausting and denoising effect of this device is unaffected.
Summary of the invention
In order to guarantee the requirement of silencing apparatus outward appearance U.S., the purpose of this utility model is to provide a kind of muffling and exhausting device with undercut embossing, is to adopt the mode of undercut embossing to be fixed in the joint of body and two end caps, not only attractive in appearance but also solid.
The technical solution of the utility model is achieved in the following ways: a kind of muffling and exhausting device of undercut embossing, by suction tude, air inlet end cap, baffler body, the end cap of giving vent to anger, steam outlet pipe, formed, two ends of baffler body are provided with air inlet end cap and the end cap of giving vent to anger, inlet end covers and is welded with suction tude, outlet side covers and is welded with steam outlet pipe, it is characterized in that: the junction of described air inlet end cap and give vent to anger end cap and baffler body has undercut turnup structure.
Described undercut turnup structure is that two ends of baffler body have respectively turned over a U shaped edge, a long limit has also been turned in two end cooperation places of air inlet end cap and give vent to anger end cap and baffler body, and with taping machine, length limit is encased to U shaped edge, make the two being interlocked tightly.
Described baffler body is pressed and is formed by galvanized coil, and two limit apposition positions adopt patterned structure.
The utility model, has reduced the raw-material waste of baffler as much as possible, eliminates optical radiation and atmospheric pollution in welding, does not also weaken the noise reduction exhaust effect of baffler simultaneously.The feature with appearance looks elegant, long service life.
